Abstract

Provided in the embodiments of the present invention are a monitoring method and apparatus, a communication device and a storage medium. The monitoring method is executed by a UE and comprises: in response to a UE being in an inactive state, determining a paging subgroup ID corresponding to a paging subgrouping manner, wherein the paging subgroup ID is used by the UE in the inactive state to monitor a wake-up signal and/or a paging message.

Description

    FIELD
  • The present invention relates to, but is not limited to, the technical field of communication technologies, and more particularly to a monitoring method and apparatus, a communication device, and a storage medium.
    • BACKGROUND
  • In the related technology, if paging is performed without paging subgrouping, all user equipment (UE) devices are woken up in for example one paging occasion (PO). Within the paging occasion, paging probabilities of the UEs are different, UE with a relatively low paging probability will also be woken up by mistake, which will cause unnecessary power consumption. Therefore, it is considered that the UEs should be grouped for paging. No matter which subgrouping method is used, the UE and the network device (such as a base station and a core network device) need to have an agreement on the paging subgroup in which the UE is located. In this way, a paging message can be sent to the UE normally.
  • When the UE is in a radio resource control (RRC) inactive state, the UE needs to monitor core network (CN) paging and radio access network (RAN) paging at the same time. At this time, there is a risk that the state of the UE considered by the network device is inconsistent with the actual state of the UE. In this case, if the UE performs the paging according to an original subgrouping, the paging message will be lost.

  • In order to better understand the technical solution described in any embodiment of the present invention, a partial description of the related technology is provided.
  • In an embodiment, if the paging subgrouping is not performed, UEs are woken up in a paging occasion. In this case, UE with a relatively low paging probability will be woken up improperly, resulting in unnecessary power consumption. Therefore, the UEs need to be grouped for paging, and the UEs are paged in a paging subgrouping mode. In an embodiment, paging subgrouping information may be carried in paging downlink control information (DCI) or in paging early indication (PEI). No matter which paging subgrouping mode is used, the UE and the network device (including a base station and a core network) need to agree on the subgroup where the UE is located before the paging message can be sent to the UE normally.
  • In an embodiment, two paging subgrouping modes are provided. One is a paging subgrouping mode based on network allocation (CN-assigned subgrouping), and the other is a random subgrouping mode based on the UE identifier (UE_ID based subgrouping), or a paging subgrouping mode based on UE-ID.
  • In an embodiment, a process of determining a paging subgroup ID (SubgroupID) according to a UE-ID paging subgrouping mode is provided. The paging subgroup ID (SubgroupID) is determined according to the following formula: SubgroupID=(floor(UE_ID/(N×Ns)) mod subgroupsNumForUEID) + (subgroupsNumPerPO - subgroupsNumForUEID); where N represents a paging frame density in a time domain, that is, the number of total paging frames in a paging period (T); Ns represents a paging density in a paging frame (PF) in the time domain, that is, the number of paging times or paging occasions in a paging frame, which may be 1, 2 or 4; UE_ID represents a identifier of a paging subgroup where a UE is located, in an embodiment, UE_ID is 5G-S-TMSI mod X, and X is 32768 if extended discontinuous reception (eDRX) is applied, otherwise, X is 8192; subgroupsnumforUEID represents the number of total paging subgroup resources used for UE_ID, for example, it indicates the number of subgroups from UE_ID based subgrouping in a PO in system information broadcast; subgroupsNumPerPO indicates the number of total subgroups that can be supported by the PO in the system information broadcast; "mod" represent a remainder function, which obtains a remainder after two numerical expressions are subjected to a division operation; "floor" represents a round down function, that is, it takes an integer no larger than a numeric expression, for example floor (3.7) = 3.
  • In an embodiment, a paging subgrouping mode based on network allocation is provided. The paging subgrouping mode based on the network allocation can be performed by the core network device as a unified node. Here, when the network allocates paging subgroup identifiers, determination is made according to attributes or statistical paging probabilities of UEs.
  • For example, RAN2#114 Agreements[2]: CN is responsible for allocating UEs to UE paging subgroups based on UE characteristics; Use same UE subgroups when in RRC_IDLE and RRC _INACTIVE.
  • Here, if the core network device does not provide the paging subgroup ID to the UE or the UE does not support the paging subgrouping mode of the network device, the UE will fall back to the paging subgrouping mode of the UE-ID to select paging subgroup resources.
  • In some application scenarios, when the UE is in an inactive state, there will be inconsistencies between UE's states maintained by the base station and the core network device. For the paging subgrouping mode based on the network allocation, the UE utilizes the subgroup determined by the paging subgrouping based on the network allocation in both the idle state and the inactive state. When the UE transitions from the idle state to the inactive state, the core network device will not assign/allocate a new subgroup. Therefore, there is no miss match problem when the UE is in the idle state and inactive state. When the UE-ID based paging subgrouping mode is used, due to different paging cycles in the inactive state and the idle state, the subgroups in the two states are different, thus causing the miss match problem.
  • The following provides a calculation example. Common assumption: RAN paging cycle=rf32; UE specific DRX value=rf64; default paging cycle=rf128; N=T; Ns=4; UE_ID=1234; N: number of total paging frames in T; Ns: number of paging occasions for a PF; UE_ID: 5G-S-TMSI mod X, where X is 32768 if eDRX is applied; otherwise, X is 8192; subgroupsNumForUEID:8. In this case, SFN for the PF is determined by: (SFN+PF_offset) mod T = (T div N) × (UE_ID mod N); Index(i_s), indicating an index of the PO, is determined by: i_s = floor (UE_ID/N) mod Ns; SubgroupID = (floor(UE_ID/(N×Ns)) mod subgroupsNumForUEID) + (subgroupsNumPerPO - subgroupsNumForUEID).
  • That is, it is assumed that a value of the RAN paging cycle is 32; a value of the UE-specific DRX cycle is 64; a value of the default paging cycle is 128; N is the number of all paging frames in one paging cycle (T); Ns is the number of paging times within the frame (PF) and is 4; a value of the UE_ID is 1234; and a value of subgroupsNumForUEID is 8.
  • SFN is determined by PF: (SFN+PF_offset) mod T = (T div N)×(UE_ID mod N); a paging occasion sequence number (Index(i_s)) indicates a sequence number of a paging occasion (PO), which is determined by the followings: i_s = floor UE_ID / N mod Ns ;
    Figure imgb0001
     SubgroupID = (floor(UE_ID/(N×Ns)) mod subgroupsNumForUEID) + (subgroupsNumPerPO - subgroupsNumForUEID).

  • The idle state in which the UE is located in the embodiments of the present invention refers to the RRC idle state; the inactive state in which the UE is located refers to the RRC inactive state.
  • In some embodiments, when the UE is in the inactive state, the UE needs to monitor CN paging and RAN paging. At this time, there may be a miss match between the network device and the UE. For example, the context of the UE is lost on the network side, and the network device thinks that the UE is in the RRC idle state, so it initiates the CN paging. At this time, the UE is still in the inactive state, and the network device considers the UE to be in the idle state.
  • As an example, an implementation of paging subgrouping is provided below. A paging subgroup may be a paging subgroup in paging DCI, or a paging subgroup using a wake-up signal. It is assumed that the UE in the idle state is assigned to subgroup 0 (that is, a paging subgroup ID is ID0), and the UE enters the inactive state or after calculation by the above formula, assuming that the RAN paging cycle is used, the UE will be assigned to subgroup 1 (that is, a paging subgroup ID is ID1). Under normal circumstances, if there is no miss match caused by the context loss on the network side, the base station sends the PEI to the UE according to subgroup ID1, and the UE monitors the PEI under subgroup ID1. However, once the context of the UE is lost on the network side (the subgroup ID1 maintained by the base station will also no longer exist), the network device thinks that the UE is in the idle state, and thus initiates CN paging. At this time, the base station determines the paging subgroup ID by using the paging cycle of the paging subgrouping mode configured by the network, that is, paging will be performed for subgroup ID0. However, the UE still uses subgroup ID1 to monitor paging, this will cause loss of the paging message or paging early indication.
  • Embodiments of the present invention provide a method for determining a paging subgroup ID to solve problems, during paging monitoring, caused by the state of the UE and the state that the network device thinks the UE is in being inconsistent.
  • As shown in FIG. 2, embodiments of the present invention provide a monitoring method, performed by the UE, including the following step.
  • In step S21, a paging subgroup ID in a paging subgrouping mode is determined in response to the UE being in an inactive state, where the paging subgroup ID is used for the UE in the inactive state to monitor a wake-up signal and/or a paging message.
  • Here, the UE may be various mobile terminals or fixed terminals. For example, the UE may be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform or a multimedia device.
  • In the embodiments of the present invention, the inactive state involved may be the RRC inactive state, and the idle state involved may be the RRC idle state.
  • In an embodiment, the paging subgrouping mode may be, but is not limited to: a paging subgrouping mode based on an ID of the UE (UE-ID).
  • In an embodiment, the wake-up signal may be, but is not limited to, PEI.
  • In an embodiment, the paging message may be any kind of paging message. For example, the paging message may be DCI.
  • Here, the paging subgroup ID is used to monitor the PEI when the paging subgroup ID of the UE in the inactive state is different from the paging subgroup ID of the UE determined by the network device.
  • Here, the paging subgroup ID is used to monitor the PEI when the state of the UE is inconsistent with the state of the UE determined by the network device. Here, the state of the UE is the RRC inactive state, and the network device determines that the state of the UE is the RRC idle state.
  • Here, the network device includes an access network device and/or a core network device. Here, the access network device may be, but is not limited to, a base station. The core network device may be, but is not limited to, various network functions or entities that implement network functions. Here, the base station may be, but is not limited to, at least one of: a 3G base station, a 4G base station, a 5G base station or other evolved base stations.
  • In an embodiment, the wake-up signal may be sent by the access network device or the core network device. If the wake-up signal is sent by the core network device, the core network device sends the wake-up signal to the base station, and the base station forwards the wake-up signal to the UE.
  • In the embodiments of the present invention, when the UE is in the inactive state, the paging subgroup ID in the paging subgrouping mode can be re-determined, so that the UE in the inactive state can monitor the PEI and/or the paging message. In this way, compared to the situation that the UE in the inactive state monitors the paging with the paging subgroup for the inactive state, and the network device performs the paging according to the paging subgroup in the idle state, the present method can reduce the loss of the paging message and improve the success rate of the paging.
  • In some embodiments, the method includes: receiving paging configuration information sent by the network device.
  • Step S21 includes: determining the paging subgroup ID in the paging subgrouping mode according to the paging confirmation information in response to the UE being in the inactive state. The paging subgroup ID is used for the UE in the inactive state to monitor the wake-up signal.
  • Embodiments of the present invention provide a monitoring method, performed by the UE, including: receiving paging configuration information sent by the network device; and determining the paging subgroup ID in the paging subgrouping mode according to the paging confirmation information in response to the UE being in the inactive state. The paging subgroup ID is used for the UE in the inactive state to monitor the wake-up signal.
  • In this way, in the embodiments of the present invention, the paging subgroup ID can be re-determined based on the paging configuration information of the network device when the UE is in the inactive state.
  • It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present invention can be executed alone or together with some methods in the embodiments of the present invention or some methods in related technologies.
  • In some embodiments, step S21 includes: in response to the UE being in the inactive state, determining the paging subgroup ID of the UE in the inactive state according to a paging subgroup ID determination mode of the UE in an idle state.
  • As shown in FIG. 3, embodiments of the present invention provide a monitoring method, performed by the UE, including the following step.
  • In step S31, the paging subgroup ID of the UE in the inactive state is determined according to a paging subgroup ID determination mode of the UE in an idle state in response to the UE being in the inactive state.
  • In some embodiments, step S31 includes one of: determining the paging subgroup ID of the UE in the inactive state as a paging subgroup ID used by the UE in the idle state; or determining the paging subgroup ID of the UE in the inactive state according to a paging cycle of the UE in the idle state.
  • Embodiments of the present invention provide a monitoring method, performed by the UE, including: determining the paging subgroup ID of the UE in the inactive state as a paging subgroup ID used by the UE in the idle state; or determining the paging subgroup ID of the UE in the inactive state according to a paging cycle of the UE in the idle state.
  • For example, when the UE is in the idle state, the paging subgroup ID determined according to the UE-ID based paging subgrouping mode is ID0. The UE determines that the paging subgroup ID in the inactive state is the paging subgroup ID used by the UE in the idle state. That is, it is determined that the paging subgroup ID in the inactive state is ID0. If the context of the UE is lost on the network side and the network device thinks that the UE is in the idle state, the determined paging subgroup ID of the UE is ID0. In this way, when the UE is in the inactive state, it can monitor the PEI in paging subgroup resource(s) configured for the paging subgroup ID being ID0, and the network device can initiate the paging such as the PEI in the paging subgroup resource(s) for the paging subgroup ID being ID0. In this way, the loss of the paging message is avoided and the paging success rate is improved.
  • For example, when the UE is in the idle state, the paging subgroup determined according to the paging cycle of the UE in the idle state is ID0. The UE determines the paging subgroup ID in the inactive state according to the paging cycle in the idle state, that is, it determines the paging subgroup ID in the inactive state is ID0. If the context of the UE is lost on the network side and the network device thinks that the UE is in the idle state, the determined paging subgroup ID of the UE is ID0. In this way, when the UE is in the inactive state, it can monitor the PEI in the paging subgroup resource(s) configured for the paging subgroup ID being ID0, and the network device can initiate the paging such as the PEI in the paging subgroup resource(s) for the paging subgroup ID being ID0. In this way, the loss of the paging message is avoided and the paging success rate is improved.
  • In this way, in embodiments of the present invention, the paging subgroup ID of the UE in the inactive state can be determined as the paging subgroup ID of the UE in the idle state, or the paging subgroup ID can be determined according to the paging cycle in the idle state. In this way, the paging subgroup ID of the UE in the inactive state for the paging can be consistent with the paging subgroup ID sent by the network device, thus reducing the paging message loss and improving the paging success rate.
  • In the embodiments of the present invention, it can not only solve the problem of the paging message loss caused by the inconsistency (due to the loss of the UE's context on the network side) between the inactive state where the UE is located and the idle state where the network device thinks that the UE is located, but also solve the problem of the paging message loss caused by the inconsistency between any state of the UE and the state of the UE considered by the network device.
  • It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present invention can be executed alone or together with some methods in the embodiments of the present invention or some methods in related technologies.
  • In some embodiments, in step S31, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state includes: based on a protocol agreement, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state.
  • Embodiments of the present invention provide a monitoring method, performed by the UE, including: based on a protocol agreement, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state.
  • Here, the protocol may be a wireless communication protocol, for example, it may be a 5G wireless communication protocol.
  • Here, the protocol may also be a protocol negotiated between the network device and the UE.
  • In some embodiments, the protocol stipulates at least one of: if the UE supports an ability of monitoring the wake-up signal, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state; if the UE supports an ability of the paging subgrouping mode based on the UE-ID, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state; if the UE supports an ability of monitoring the wake-up signal and supports the paging subgrouping mode based on the UE-ID, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state; or if the UE currently uses the paging subgrouping mode based on the UE-ID, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state.
  • Here, the UE currently uses the UE-ID-based paging subgrouping mode, which implicitly that the UE supports the ability of monitoring the wake-up signal and the UE-ID based paging subgrouping mode, and the network device also has the ability of supporting the UE-ID based paging subgrouping.
  • In some embodiments, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in step S31 includes at least one of: determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE supporting an ability of monitoring the wake-up signal; determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE supporting an ability of the paging subgrouping mode based on the UE-ID; or determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE supporting an ability of monitoring the wake-up signal and supporting an ability of the paging subgrouping mode based on the UE-ID.
  • If the UE is currently using the UE-ID based subgrouping mode (implying that the UE supports monitoring the wake-up signal and supports the UE-ID based paging subgrouping mode, and the network also has a subgrouping ability of supporting the UE-ID based paging subgrouping mode), the paging subgroup ID of the UE in the inactive state is determined according to the paging subgroup ID determination mode of the UE in the idle state.
  • As shown in FIG. 4, embodiments of the present invention provide a monitoring method, performed by the UE, including the following step.
  • In step S41, the paging subgroup ID of the UE in the inactive state is determined according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE supporting an ability of monitoring the wake-up signal; and/or the paging subgroup ID of the UE in the inactive state is determined according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE supporting an ability of the paging subgrouping mode based on the UE-ID; and/or the paging subgroup ID of the UE in the inactive state is determined according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE supporting an ability of monitoring the wake-up signal and supporting an ability of the paging subgrouping mode based on the UE-ID.
  • In some embodiments of the present invention, the wake-up signal is the wake-up signal in the above-mentioned embodiments. For example, the wake-up signal includes the PEI.
  • For example, if the UE is in the inactive state, and the UE supports the ability of monitoring the wake-up signal and/or supports the UE-ID based paging subgrouping mode according to the protocol, the UE may determine that the paging subgroup ID is the paging subgroup ID in the idle state.
  • In embodiments of the present invention, the UE can directly determine the paging subgroup in the inactive state according to the paging subgroup ID of the UE in the idle state when the UE supports the ability of monitoring the wake-up signal and the paging subgrouping mode based on the UE-ID. In this way, there is no need for the network device to send instructions such as network signaling, interaction of network signaling can be reduced and the power consumption of the network device and the UE can be reduced.
  • It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present invention can be executed alone or together with some methods in the embodiments of the present invention or some methods in related technologies.
  • In some embodiments, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in step S41 includes: determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in response to both the UE and the network device supporting a predetermined ability; determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE and/or the network device supporting a predetermined ability.
  • As shown in FIG. 5, embodiments of the present invention provide a monitoring method, performed by the UE, including the following step.
  • In step S51, the paging subgroup ID of the UE in the inactive state is determined according to the paging subgroup ID determination mode of the UE in the idle state in response to both the UE and a network device supporting a predetermined ability; or the paging subgroup ID of the UE in the inactive state is determined according to the paging subgroup ID determination mode of the UE in the idle state in response to the UE and/or the network device supporting a predetermined ability.
  • In some embodiments, the predetermined ability is used to indicate an ability of determining a PO in the inactive state according to a PO in the idle state.
  • In an embodiment, the UE supports the predetermined ability, which may indicate that the UE supports an ability of using the PO in the idle state when the UE is in the inactive state; and/or the network device supports the predetermined ability, which may indicate that the network device supports an ability of determining a PO of RAN paging in the inactive state according to an idle state PO.
  • In an embodiment, step S51 may be determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state in response to the predetermined ability supported by the UE and the predetermined ability supported by the network device being consistent.
  • Here, if the UE supports the ability of using the PO in the idle state when the UE is in the inactive state, and the network device supports the ability of determining the PO of the RAN paging in the inactive state according to the idle state PO, the predetermined ability supported by the UE is consistent with the predetermined ability supported by the network device.
  • In an embodiment, in step S51, determining the paging subgroup ID of the UE in the inactive state according to the paging subgroup ID determination mode of the UE in the idle state may indicates that determining the paging subgroup ID of the UE in the inactive state according to one of ability information of the UE or ability information of the network device.
  • In some embodiments, the predetermined ability includes at least one of: a first ability used to indicate an ability of determining an inactive state paging occasion according to an idle state paging occasion; a second ability used to indicate an ability of determining an inactive state paging subgroup according to an idle state subgroup; a third ability used to indicate an ability based on an access network of determining a paging occasion of radio access network (RAN) paging in the inactive state according to an idle state paging occasion; or a fourth ability used to indicate an ability based on an access network of determining a paging subgroup for sending the wake-up signal under RAN paging in the inactive state according to an idle state paging subgroup.
  • Here, the ability information of the predetermined ability includes, but is not limited to, one of: first ability information, second ability information, third ability information or fourth ability information. The first ability information is ability information indicating the first ability, and /or the second ability information is ability information indicating the second ability, and/or the third ability information is ability information indicating the third ability, and/or the fourth ability information is ability information indicating the fourth ability.
  • Here, the first ability information and/or the second ability information may be ability information of the UE. The third ability information and/or the fourth ability information may be ability information of the network device.
  • For example, the UE has an ability of supporting InactiveStatePO-Determination, which indicates whether the UE supports to use the same i_s to determine PO in RRC_INACTIVE state as in RRC_IDLE state. When UE supports PEI reception, it also indicates whether the UE supports to use the same UE-ID based subgroup in RRC_INACTIVE state as in RRC_IDLE state.
  • In embodiments of the present invention, if both the network device and the UE support the predetermined capability, that is, when they support the ability of determining the inactive PO according to the idle state PO, the paging subgroup ID of the UE in the inactive state may be determined according to the paging subgroup ID determination mode of the UE in the idle state. In this way, the paging message loss can be reduced and the paging success rate can be improved.
  • It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present invention can be executed alone or together with some methods in the embodiments of the present invention or some methods in related technologies.
  • As shown in FIG. 6, embodiments of the present invention provide a monitoring method, performed by the UE, including the following step.
  • In step S61, the paging subgroup ID of the UE in the inactive state is determined according to one of ability information of the UE or ability information of the network device in response to at least one of the UE or the network device not supporting a predetermined ability.
  • In some embodiments of the present invention, the predetermined capability may be the predetermined capability in the above embodiments. For example, the predetermined ability information may be at least one of the first ability, the second ability, the third ability information, or the fourth ability.
  • In an embodiment, at least one of the UE or the network device does not support the predetermined ability, which may indicate that the predetermined ability supported by the UE is inconsistent with the predetermined ability supported by the network device. For example, the UE supports an ability of the inactive state PO and the network device supports the PO ability of determining a PO of RAN paging in the inactive state according to the idle state PO, this means that the predetermined capability supported by the UE is inconsistent with the predetermined capability supported by the network device.
  • In some embodiments, the ability information of the UE includes, but is not limited to, at least one of: first ability information used to indicate an ability of determining an inactive state paging occasion according to an idle state paging occasion; or second ability information used to indicate an ability of determining an inactive state paging subgroup according to an idle state subgroup.
  • In some embodiments, the ability information of the network device includes, but is not limited to, at least one of: third ability information used to indicate an ability based on an access network of determining a paging occasion of RAN paging in the inactive state according to an idle state paging occasion; or fourth ability information used to indicate an ability based on an access network of determining a paging subgroup for sending the wake-up signal under RAN paging in the inactive state according to an idle state paging subgroup.
  • In some embodiments, in step S61, determining the paging subgroup ID of the UE in the inactive state according to one of the ability information of the UE or the ability information of the network device includes at least one of: determining the paging subgroup ID of the UE in the inactive state according to the first ability information of the UE; determining the paging subgroup ID of the UE in the inactive state according to the second ability information of the UE; determining the paging subgroup ID of the UE in the inactive state according to the third ability information of the network device; or determining the paging subgroup ID of the UE in the inactive state according to the fourth ability information of the network device.
  • Embodiments of the present invention provide a monitoring method, performed by the UE, including at least one of: determining the paging subgroup ID of the UE in the inactive state according to the first ability information of the UE, where the first ability information is used to indicate an ability of determining an inactive state paging occasion according to an idle state paging occasion; determining the paging subgroup ID of the UE in the inactive state according to the second ability information of the UE, where the second ability information is used to indicate an ability of determining an inactive state paging subgroup according to an idle state subgroup; determining the paging subgroup ID of the UE in the inactive state according to the third ability information of the network device, where the third ability information is used to indicate an ability based on an access network of determining a paging occasion of RAN paging in the inactive state according to an idle state paging occasion; or determining the paging subgroup ID of the UE in the inactive state according to the fourth ability information of the network device, where the fourth ability information is used to indicate an ability based on an access network of determining a paging subgroup for sending the wake-up signal under RAN paging in the inactive state according to an idle state paging subgroup.
  • Here, the first ability may be inactiveStatePO-Determination; and/or the second ability may be inactiveStateSupgroup-Determination; and/or the third ability information may be ranPagingInIdlePO; and/or the fourth ability information may be ranPagingInIdleSubgroup.
  • As an embodiment, in response to both the UE and the network device supporting the predetermined ability, the paging subgroup ID of the UE in the inactive state is determined according to the paging subgroup ID determination mode of the UE in the idle state. The predetermined ability supported by the UE is the first ability. The predetermined ability supported by the network is the third ability. For example, the first ability may be inactiveStatePO-Determination, and the third ability may be ranPagingInIdlePO. For example, in RRC_INACTIVE state, if the UE supports inactiveStatePO-Determination and the network broadcasts ranPagingInIdlePO with value "true", the UE shall use the same subgrouping ID for UE-id UE_ID based subgrouping as for RRC_IDLE state. Otherwise, the UE determines the subgrouping based on the formula above.
  • For example, the second ability may be inactiveStateSupgroup-Determination. For example, in RRC_INACTIVE state, if the UE supports PEI, the UE shall use the same subgrouping ID for UE-id UE_ID based subgrouping as for RRC_IDLE state.
  • For example, the third ability may be ranPagingInIdlePO. For example, it indicates that the network supports to send RAN paging in PO that corresponds to the i_s as determined by UE in RRC_IDLE state, see TS38.304 [20]. If PEI-Config is present in SIB 1 and the UE supports inactiveStatePO-Determination, it also indicates that the network supports to send PEI for RAN paging in subgroup that corresponds to the subgroup as determined by UE in RRC_IDLE state, see TS38.304 [20].
  • Here, the first ability and/or the third ability may be abilities in the existing 5G communication protocol. For example, the first ability and the third ability may be inactiveStatePO-Determination and ranPagingInIdlePO, respectively. For example, the first ability and the third ability may be abilities newly defined in the above embodiments. The second ability and/or the fourth ability may be newly defined abilities. For example, the second ability and the fourth ability may be inactiveStateSupgroup-Determination and ranPagingInIdleSubgroup, respectively. The specific naming of the first ability, the second ability, the third ability and/or the fourth ability is not limited here.
  • In this way, in embodiments of the present invention, when the UE and the network device do not support the predetermined ability, the paging subgroup ID of the UE in the inactive state can be determined based on the ability information supported by the network device and the UE respectively. In this way, flexible determination of the paging subgroup ID of the UE in the inactive state can be adapted to various application scenarios.
  • In some other embodiments, if the UE and the network device do not support the predetermined ability, the UE can determine the paging subgroup ID of the UE in the inactive state according to the formula: SubgroupID = (floor(UE _ID/(N × Ns)) mod subgroupsNumForUEID) + (subgroupsNumPerPO - subgroupsNumForUEID). In this formula, the paging cycle is the paging cycle of the UE in the inactive state. In this case, miss match problem may occur.
  • It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present invention can be executed alone or together with some methods in the embodiments of the present invention or some methods in related technologies.
  • Embodiments of the present invention provide a monitoring method, performed by the UE, including: receiving paging configuration information, where the paging configuration information is used to indicate at least one of: first ability information of the first ability of the UE; second ability information of the second ability of the UE; third ability information of the third ability of the network device; or fourth ability information of the fourth ability of the network device.
  • In some embodiments, the paging configuration information is used to instruct the UE in the inactive state to determine the paging subgroup ID in the paging subgroup mode, and the paging configuration information includes ability indication information, where the ability indication information is used to indicate at least one of the first ability information of the UE, the second ability information of the UE, the third ability information of the network device, and the fourth ability information of the network device.
  • In this way, in embodiments of the present invention, the UE can obtain the ability information of the UE and/or the ability information of the network device by receiving the paging configuration information.
  • In some embodiments, receiving paging configuration information includes: receiving a network signaling carrying the paging configuration information.
  • Embodiments of the present invention provide a monitoring method, performed by the UE, including: receiving a network signaling carrying the paging configuration information.
  • Here, the network signaling includes a dedicated signaling or a broadcast signaling.
  • Here, the network signaling may be, but is not limited to, at least one of: a media access control element (MAC CE), a RRC signaling, and a DCI. Here, the RRC signaling may be, but is not limited to, an RRC release message or an RRC reconfiguration message.
  • For example, an RRC release message sent by the network device is received. The RRC release message carries the paging configuration information. The paging configuration information is used to indicate at least one of the first ability information of the UE, the second ability information of the UE, and the third ability information of the network device and the fourth ability information of the network device.
  • In this way, in embodiments of the present invention, the UE can learn the ability information of the network device and/or the ability information of the UE by receiving the network signaling carrying the paging configuration information sent by the network device. If the UE learns the ability information of the network device and/or the ability information of the UE by receiving the RRC release message or the RRC reconfiguration message, the two functions can be implemented through one RRC signaling. For example, when the RRC release message is received, an RRC release message can be used to realize connection release and notification of the ability information of the network device and/or the ability information of the UE. For example, when the RRC reconfiguration message is used, the RRC reconfiguration message can be used to realize UE reconfiguration and notification of the ability information of the network device and/or the ability information of the UE. This can reduce signaling interactions, and reduce the power consumption of the network device and the UE.
